In assembling the prefabricated house described above, the first storyfloor panels 3 are laid on the foundation pedestals l and independentfoundation 2. The abutting edges of the adjoining first story floorpanels 3 are bonded together by a bonding agent. In laying the firststory floor panels 3 on the individual foundation pedestals 1, theanchor bolts 7 are inserted through the respective anchor bolt insertionholes 12 of the first story floor panels 3, which are then securely tiedto the on the anchor bolts 7 (see FIG. 2). Then, the first story wallpanels 4 are bonded at the coupling end thereof to the, coupling edge ofthe corresponding first story floor panels 3 by a bonding agent, and arerigidly fastened thereto by threaded nails 14 (see FIG. 2). Also, thepartition wall panel 22 and the sliding door frame wall panel 24 arerigidly fastened to the predetermined portions of the first story floorpanels 3 to define rooms 50, 51 and 52.

Then, the second floor panels 3a are bonded at the coupling ends thereofto the corresponding notches 9 formed in the frames of the first storywall panels 4 by a bonding agent, and are rigidly fastened thereto bythreaded nails (see FIG. 4). Also, some of the second story floor panels30 over the partition wall panel 22 and the sliding door frame wallpanel 24 are rigidly fastened thereto by threaded nails (see FIG. 5 and8).

Then, the first story ceiling panel 5 is placed at opposite ends thereofon top of the inner wall panel 24 and in the notch 9 formed in the frame8 of the corresponding first story wall panel 4, and bonded thereto by abonding agent. Thus, the rooms 50, 51 and 52 are completely defined bythe respective floor panels, wall panels, and ceiling panel.

Then, the second story wall panels 4a are erected above some of thefirst story wall panels 4 and the sliding door frame wall panel 24. Theadjoining first story and second story wall panels 4 are rigidlyfastened to the coupling edge of the second story floor panel 3areceived in the recess 19 defined by the adjacent notches formed intheir frames 8 and 8a by threaded nails 20. The abutting faces of thesepanels are bonded together by a bonding agent (see FIG. 4). The secondstory wall panel 4a above the sliding door frame wall I panel 24 has itsframe 8a bonded at the notch 9 thereof to the corresponding end of thesecond story floor panel 3a by a bonding agent, and is rigidly fastenedthereto by threaded nails 25 (see FIG. 5). Also, the partition wallpanel 22a and the sliding door frame wall panel 22 are rigidly fastenedto the predetermined portions of the second story floor panels 3a andthe second story ceiling panels 5a, thus defining rooms 53, 54 and 55Then, the first story roof deck 6 is placed on the first story ceilingpanel 5, with its one edge inserted in the gap 26 formed between theceiling panel 5 and the frame 8a of the corresponding second story wallpanel 4a and the angle-shaped cutwater iron plate 29 partly inserted inthe second story wall panel 4a placed on the end ridge of the roof deck6 and fastened thereto by roof deck rivet bolts 38. The roof deck 6 isalso supported on the horizontal portion 36 of the roof deck attachmentmetal 33, which is secured to the frame 8 of the corresponding firststory wall panel 4 by the fastening bolt 30, and tied thereto by roofdeck rivet bolts 38. Similarly, the second story roof deck 6a is alsotied to the second story ceiling panel 5a through the roof deckattachment metal 33. In the above manner, the prefabricated house asshown in FIG. 1 is completed.

FIGS. 10, 11 and 13 show modifications of the roof deck attachment metalaccording to the invention.

In the modification of FIG. 10, the attachment metal 33 has a zigzagshape consisting of alternate hill portions 56 and valley portions 57and having a plurality of grooves 58. The hill portion 56 has ahorizontal top 58 provided with outwardly extending roof deck rivetbolts 38. The roof deck 6, whose insertion holes are fitted on therespective roof deck rivet bolts 38, may be rigidly attached to the roofdeck attachment metal 33 by fastening nuts 60 fitted on the rivet bolts.The attachment metal 33 is rigidly fastened to the frame 80 of the wallpanel 6a by means of the fastening bolts 30.

In the modification of FIG. 11, the roof deck at tachment metal 33 hashill and valley portions 56 and 57 engaging a roof deck 6, which isfirmly secured thereto by roof deck rivet bolts 38. The roof deckattachment metal 33 is rigidly tied to a second story wall panel 4a bymeans such as threaded nails 61.

In the modification of FIGS. 13 and 14, an angular fitting metal isdesignated at 62. A roof deck attachment metal 33 having alternate hilland valley por-.

tions is rigidly fastened, 'for example by means of screws, with itsvalley portions 330 to the flange 63 of the metal 62. Spaced from thevalley portion 33a is a plate 64 having an U-shaped section, both sideflaps 64a of which (one of which is illustrated in FIG. 13) lie alongtheinside tapered faces of the roof deck attachment metal 33. A facing (orcut-off wall) 65 is rigidly secured, for example by spot-welding, at itslower edge to the plate 64. The facing 65 is formed substantially tosuit to the shape of the valley portion of the metal 33 and adapted tobe assembled from one side. Formed at the lower end of the facing 65 isa V -shaped groove 66 produced by folding, from the upper part of whichan upright flap 67 extends and is bent at the top into a horizontal flap68. This horizontal flap 68 is rigidly secured, for example by means ofbolts to the hill portions 69 of the attachment metal 33. A V- shapedgroove 71 is formed by the inclined flap 70 of the cut-off wall 65 andthe inclined surface of the attachment metal 33. Therefore, a room forreceiving the roof deck results along the valley portionof thecut-offwall 65. Inserted into these grooves is the end portion of the roof deck6. The gap between the inserted end 60 and the walls of the grooves isfilled with a calking material 72, thus ensuring water-tightness.

As has been described in the foregoing, according to the invention floorpanels, wall panels and. ceiling panels are united together at least bybonding the abutting faces by a bonding agent, so that a rigid unitaryhouse structure may be obtained extremely simply. Also, theprefabricated house according to the inven tion can be assembled from aminimum number of standard construction elements. Further, it ispossible to construct a house structure fully meeting the detaileddemands of user. Furthermore, the coupling between a first story wallpanel, a second story wall panel, and a second story floor panel, thecoupling between the first story wall panel, the second story floorpanel and a ceiling panel and the coupling between a partition wallpanel and a non-partition wall panels are achieved by driving threadednails in a T-shaped fashion, so that rigid coupling may be obtainedwithout using any metal joiner. Also, the comer wall panels may berigidly joined together by driving threaded nails and without using anymetal joiner. Further, the roof deck may be firmly tied to the wallpanels such that it will not rattle or will not be detached even if itis subjected to a strong blowing-up wind. Further, the leaking of rainwater maybe prevented by virture of the cutwater iron plate provided atthe junction of the roof deck provided on a ceiling panel and wallpanels. Further, by virture of the roof deck attachment metal, the roofdeck may be attached extremely simply and speedily and may be supportedstably. Also, the roof deck attachment metal can increase the strengthof the attachment without impairing the appearance.
